I am looking for a concise way to write “a message to myself”. Message could be replaced with letter or mail. In context, I'm using this word to represent a digital message I have written to myself for the purpose of reading later. The best I have is “meta mail” but this is my own creation.
I have an inbox full of _____.
Thesaurus search terms: Message, Letter, Mail
Criteria: A single word, character, or compound word will be considered.
Considerations: Meta Mail: This isn't ideal because it is two words.
Alternatives: Phrases are welcome as inspiration, but unlikely to be used.
